Breaking Away from Traditional Moving-Bed Designs

Engineered from the Ground Up for Total Stability

Most CoreXY printers move the heated bed during printing, which causes the model to shake. ARCO uses a fixed heated bed that keeps the print steady while its flying gantry lifts the printhead with precision. Like an F1 car accelerating with perfect control, ARCO delivers both speed and stability in every layer.

ARCO Reinforces Stability Right from Its Structure

Animation of a typical FDM 3D printer structure with a moving print bed highlighting reduced stability.

Typical FDM Structure

When the bed moves, the print moves with it, introducing vibration and a less stable center of gravity. That’s why large prints are more prone to failures, layer shifts, and stringing.

ARCO's Optimized Structure

ARCO keeps the model firmly on the heated bed, reducing vibration and maintaining a lower center of gravity. The result is steadier large-scale printing with fewer failures, less layer shifting, and less stringing.

Details Matter. ARCO Delivers Rock-Solid Stability

ARCO FDM 3D printer extruder with industrial-grade heat pipe for efficient cooling and smooth, clog-free filament extrusion.

ARCO is the first to bring patented industrial-grade heat pipe technology to FDM printing. Paired with a huge 18 mm gear, this system cools efficiently and shortens the distance between the extrusion gear and nozzle, delivering stronger torque and higher flow for smoother, clog-free printing.

ARCO DEP Extrusion: High Stability, Maximum Precision

Standard extrusion diagram showing lower stability and less consistent feeding than ARCO.

Standard Extrusion

A longer extrusion path makes feeding less stable and more prone to jams. Smaller gears also mean weaker torque and lower flow, so print quality can vary from material to material.​

ARCO DEP extrusion diagram showing higher stability and more precise feeding than standard extrusion.

ARCO DEP Extrusion

ARCO DEP uses an ultra-short extrusion path for smoother, more precise feeding. Larger gears deliver stronger torque and higher flow, helping maintain consistent quality across a wide range of materials.

From Cosplay Props to Rapid Prototypes, ARCO Handles It All

Is ARCO good for printing cosplay helmets and armor?

Yes. The 300 × 300 × 300 mm³ build volume lets you print full-size helmets, shoulder pads, and gauntlets in one piece without splitting. At 40,000 mm/s², a standard helmet can be completed in under 6 hours. With the PentaShield enclosure, you can print ABS and ASA without filling your space with fumes. KOL GodFinger’s Kampfer build was printed entirely on ARCO.

Can ARCO keep up with a design studio's prototyping pace?

Yes. A 15 cm functional prototype that takes 8+ hours on a conventional printer finishes in under 3 hours on ARCO. The 300°C hotend handles PLA, PETG, ABS, TPU, nylon, and carbon-fiber composites, test different materials without switching machines. Klipper lets you optimize speed profiles per material.

Is ARCO a good first large-format FDM printer for a home maker?

Yes. Auto-leveling, PEI flex plate, and clog-resistant DEP extrusion mean fewer failed prints for beginners. Start with PLA at default settings, then grow into PETG, TPU, and beyond as your skills develop. The Klipper web interface gives advanced users full control, while beginners can just load and print.

FAQ

Is the Phrozen ARCO reliable for single-color printing?

Yes. Reviewers consistently call single-color printing “very reliable.” DEP extrusion minimizes clogs, while the fixed-bed CoreXY design reduces layer shifts on tall prints. Some testers even report better results than Bambu X1C.

What materials can the ARCO print?

PLA, PETG, ABS, TPU, nylon, ASA, PC, and carbon/glass fiber composites. The 300°C hotend covers all standard and engineering-grade filaments. For ABS, nylon, and PC, pair with the PentaShield enclosure to stabilize chamber temperature and filter fumes.

How does ARCO compare to Bambu P2S or H2S?

ARCO offers higher acceleration (40,000 vs ~20,000 - 36,000 mm/s²), a larger build volume (300 x 300 x 300 vs 256 x 256 x 256 mm), patented DEP extrusion, and an open Klipper system. Bambu uses a closed ecosystem.

Does ARCO need an enclosure?

Not for PLA or PETG. The optional PentaShield enclosure is recommended for ABS, nylon, PC, and carbon fiber composites, it maintains stable chamber temperature, cuts noise by 15%, and filters odors. It’s also useful for home or classroom environments where quiet operation matters.

What is DEP extrusion and why does it matter?

DEP (Direct Extrusion Path) is Phrozen's patented hotend design. An industrial heat pipe keeps the melt zone short, so filament doesn't soften and jam in the wrong spot, that's heat creep, the #1 cause of clogs in FDM. The 18 mm dual gear delivers 9.5 Nm torque, handling everything from TPU to carbon fiber. Fewer clogs means fewer failed overnight prints.

Is ARCO good for printing large models overnight?

Yes. The DEP extrusion system virtually eliminates clogging, and the fixed-bed design prevents layer shifts on tall prints. Material breakage detection pauses the print if filament runs out. The built-in 720p camera lets you monitor remotely. Users report successful overnight prints of 20+ hour models.

What slicers work with ARCO?

Phrozen Orca is the official and recommended slicer for ARCO, optimized for performance and actively maintained. ARCO runs on an Klipper system, so any slicer that exports standard G-code is also compatible.

Is ARCO noisy during printing?

ARCO is designed to reduce noise with its enclosed structure and optimized motion system. With the PentaShield enclosure, noise can be reduced by up to 15%, making it suitable for home, studio, or classroom environments.

Is ARCO difficult to set up?

No. ARCO comes pre-assembled and requires minimal setup. With auto-leveling, most users can start printing within minutes.*
